A polar bear starts at the North pole. It travels 1km South, then 1km East, then 1km North to return to its starting point. This trip takes 0.5h. What was the bear's average velocity (in km/h)?

Total distance travelled = 1 + 1 + 1

= 3 km

Total time taken = 45 min

=  hours

=  hours

Average speed =  

= 3 ÷  

= 3 x  

= 4 km/hr

So, the bears average speed was 4 km/hr

0

Step-by-step explanation:

The polar bear's net distance traveled is 0 km since it ends up at the same point it started.

velocity = 0 km / 0.5 h = 0

0

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
